The planet Mars has no international discipline, though scientists consider it did have one sooner or later up to now. Earlier research recommend that when Mars’ international magnetic discipline was current, it was roughly the identical power as ’s present discipline. Surprisingly, devices from previous Mars missions, each orbiters and landers, have noticed patches on the planet’s floor which are strongly magnetized—a property that would not have been produced by a magnetic discipline just like Earth’s, assuming the rocks on each planets are comparable.


Ahmed AlHantoobi, an intern working with Northern Arizona College , assistant professor Christopher Edwards and postdoctoral scholar Jennifer Buz in NAU’s Division of Astronomy and Planetary Science, led a examine searching for solutions to elucidate these magnetic anomalies. The group explored the relationships between the power of the magnetic discipline on the floor and the composition of the crust within the Terra Sirenum-Terra Cimmeria area of Mars.

“Our present that within the space with the magnetic patches, there’s a verifiable optimistic correlation between the magnetic discipline and mineralogical information,” mentioned AlHantoobi. “This leads us to consider that the composition of these patches allows them to report the magnetic discipline exceptionally nicely. Subsequently, Mars’ historic international didn’t have to be as to provide the strongly magnetized crust we observe in the present day.”

The group just lately revealed their findings within the journal Geophysical Analysis Letters in a paper entitled, “Compositional Enhancement of Crustal Magnetization on Mars.”

AlHantoobi, a scholar at Khalifa College within the United Arab Emirates (UAE), spent the two summers collaborating in a program supplied at NAU by Edwards and Buz to coach and mentor Emirati in analysis. This system is a part of Edwards’ involvement within the UAE house company’s Emirates Mars Hope orbiter mission, which carries a novel new instrument he co-designed in collaboration with engineers from the United Arab Emirates Mohammed bin Rashid House Centre (MBRSC) and Arizona College (ASU). Whereas AlHantoobi was in a position to be on campus throughout the summer season of 2019, with the intention to proceed his mission throughout the summer season of 2020 and abide by , the group was pressured to adapt to the 11- time distinction between Dubai and Flagstaff.

“The affect of this examine is sort of excessive,” mentioned Edwards, “because it supplies among the first solutions to particulars associated to the magnetism of the Martian crust.”

“My analysis with Jennifer and Christopher was an eye-opening expertise,” mentioned AlHantoobi, “and I consider it has impacted what I need to be sooner or later. I received to expertise first-hand the fantastic thing about discovering and answering the unknown.”
